Specification forming part of Letters Patent No. 184,-684,'dated November 21,1876; application filed April 4,1876.

' Toall whom it may concern Be it known that vI, WILLIAM A. WRIGHT, of Augusta, Richmond county, Georgia, have invented Improvements in Baling-Presses, of which the following is-thespecification:

My invention relates to certain improve 'a-side elevation, partly in section, of the improved press; Fig. 2, a sectionalelevation on the line w a), Fig. 1; Figs. 3, 4,'and 5, detached views of parts of the press; Fig. 6, a modification; and Figs. 7 to 10, diagrams,:representing different modes in which the press may be used.

The base of the press consistsof parallel beams B B, and cross-pieces A A bolted .together. To the four corners of the base-are securely bolted the lower ends of *four metal rods, Gr Gr G G, which are parallel tothesides of the bailing-chest, but atthe points-511,01)- posite the upper end of the chest, are bent and converge from the narrowsides, at an angle of about seventy degrees,-toward the center of the head-block H, :each rod Gheing bolted to one of four radiating arms, h, of the said head-block. Theupper half of the baling-chest consists of abox, D, strengthened externally by cross-bars b b, the latterbeing bolted to the narrow sides, and extending beyond the rods G,-'as shown in Fig. 2, for a purpose described hereafter. The portion D of the. baling-chest is suspended "between the rods G by means of brackets E, each secured by a set-screw, 0 to one of the rods, and consisting of a hub, c, and arms 0 0 at right angles, recessed to receive the ends of the adjacent cross-bars b b, where they meet, and bolted to the latter, as shown in Figs. 1 and 4. The lowerportion of the baling-chest consists of detachable end pieces D and side pieces D the latter being hung to-the frame of the apparatus, so as tobe turnedoutward to the position shown in dotted lines, Fig. 2. In the present instance the hinges for the side pieces -D are formed by rounding the project- ;ing' ends a e ofa cross-piece, d, on each side piece D to fit sockets in adjustable brackets E, sliding on the rods G, Fig.3. Thesaid slots a are of such alength that the block'O can be moved lengthwise in the direction of the arrow, Fig. -1,-:until-its inner end isfree from the crossbar A, when it may be turned to a position at right angles to the beams B,

exposing the :end of -the:baling-chamber. A detachable cross-bar, A is bolted to the under sides of .the beams B, and has in the center a-bearing-plate, afl-forthe purposedescribed hereafter. To'ithe usual screw Lof the .follower Pis fitted the nut I,the hollow threaded sleeve 420i =which fits nicely, but so as to turn freely, .in the head-'block'lH, re-

.cesses as being formed bycutting away the threads'within the 'nut,=soas to leaveitwo or more th readed bearings, 8, thus reducing the frictional surfaces, and atlbrdingphambersfor the retention of :the lubricant. The headblock .H and nut I haveannular inclined ribbed bearing-faces t, between which intervene a series of rconical grooved rollers, g, which reduce the-friction between the surfaces,while =theannular ri'bs.t,.upon or forming apart of the bearing-faces, retain "the :rollers in their positions without interferingwith the freedom of their movements. A=detachableflanged ring, K, incloses and is bolted to, so as-to form partof the :sleeveof thenut at -the upper end, and-in grooves formed in the said ring, and in ;the adjacent end'of the headblock H are confinedfriction-balls m. Strips of wood f are passed between thesides of the baling-box and the -=rods .G,=to hold the sides in position. The cross beam or yoke by which the nut I is turned is secured-t0 the flangeof the ring K, and the screw and follower are elevated, as usual, to expose the mouth of the chamber into which the material to be pressed is thrown, the balls m reducing the friction between-the head-block and the nut, as the latter is turned in elevating the follower.

The movement of the nut I is reversed, after filling the chamber, so as to condense the material between the follower P and the pressing-block O, the head-block resistingthe upward thrust of the screw, the rollers g reducing the friction between the head-block and the revolving nut, and the rods Gr so distributing the strain between the head-block and the base as to prevent any, undue pressure upon any part of the apparatus.

By bending the rods Gr ,so that their upper ends converge toward theaxis of the screw, the strains are brought in a direct line, and all torsional strains thereby avoided, and, by bending rods at an angle of seventy degrees, or thereabout, I prevent the tendency to force the rods inward against the box, without uu duly increasing the height of the machine.

In order to facilitate the transportation of the machine, hooked rods N are-hung to studs on the rods Gr, so as to hook beneath the axle of a truck, as shown in dotted lines, Fig. 2. On drawing the truck forward the press is tilted until it falls in anearly-balanced position upon the axle, when a slight pressurewill lift its base free from the ground.

Owing to the manner above described of constructing a press, it may, by a simple adjustment of its parts, be adapted for use in various positions, as circumstances may require. If, for instance, a rotating box-press is required, the cross-bar A is secured in position, a suitable bearing is placed beneath the block a, elevating the base from the ground, and thering K is bolted to a stationary crdsspiece, t, as in diagram, Fig. 7. The box may then be rotated on its vertical axis, the lower bearing being at the point to.

If hand-power is to be used, the press is suspended with its hearings or cross-pieces b resting upon the floor of the gin-house, as shown in Fig. 8.

.In order to press upward, the press is inverted, the lower bearing being upon the ring K, and the plate a forming the upper hearing, asishown in Fig. 9, when the box may be revolved; or theinverted press may rest in a stationary position, with the bearings or crosspieces b upon the floor of the gin-house, as shown in Fig. 10. In the latter case the press is fed from the top, the pressure-block 0 be ing slid to one side and turned upward to expose the mouth of the baling-chamber, as before described. g

When thepressis to be used in an inverted position the brackets E are applied to the opposite edges of the cross-bars b, so as to support the latter from beneath.

While the bars G support the base, headblock, and the portion D of the baling-chest in their proper relative positions, they permit the hinged sides D to be turned outward and the detachable sides D to beremovcd, so as to allow free access to the material compressed between the follower and the pressure-block, completely exposing the pressing-chamber T at all sides- I Instead of bolting the upper ends of the .rods Gr directly to the head-block, the rods at each end of the press may consist of asingle continuous bar, bent to form a loop which is passed around a block, I, bolted to the headblock, as shown in Fig. 6. a

Although the'bars b have been referred to as constituting the center bearing of the press, it will be apparent that lugs or brackets or staples or openings may be arranged soasto secure a rest or hearing, on which the press may be supported at or near its center. :Other means, also, may be adopted for securing a proper central hearing at the point to. q

The brackets E not only support the balingbox, but also serve to prevent the rods G from spreading. Gross-bars E may, however, be employed to give increased rigidity to the structure. l

I do not claim, broadly, rollers arranged between the head-block and the flange of the nut, as this is old; but i a p I claim- 1. The combination, with the baling-chest, of a pressure-block, O, hung to the frame so that it maybe turned outward to expose the end of the baling-chamber, substantially as i specified. r

V 2. The head-block, provided with anannular rib, t, on its lower face, in combination with the flange of the nut I, having a similar rib, and with intervening tapering grooved rollers, as set'forth. 1

3. The nut I, recessed to form detached threaded bearings and intermediate oil-chambers m, as described.

4. A baling-press, provided with side bearings at b and with an end hearing at w,whereby it may be supported with eithcrend uppermost, either in a stationary position or ,1 so as to revolve on its vertical axis, as specified. l

5. The combination of the press and the hooked arms or rods N, as and for the pur pose set forth.

6. The brackets. E, secured to. the rods G, and having forked ends bolted tothe balingchest, as specified.

7. The brackets E, having bearings for the journals of the doors or sides D and connected by tie-rods e, substantially as set forth.

.In testimony whereof I. have signed my name to this specification in the presencegof two subscribing witnesses.
